Neil Have you entertained the idea of making a square collet and a custom parting tool to finish the head of the bolt. I think the time to be a lot less than the 7 minutes. If is going to make a big difference on your set up. Good luck, I'll be watching Nelson

Reuben Sounds like you have a plan. Keep us up on your progress. It all sounds good. Nelson

I started casting in the 90's and have melted everything from aluminium to bronze and many alloys in between. I have read my share of so called bad effects from water and wet concrete. I have never tested fate but it is not as dangerous as most play it up to be. Molten metal is the biggest...

Giovanni You might want to seek the help of a blacksmith. Even if you could cast, the machine work would set you back more than you think. Nelson

I have a good friend that can no longer use his equipment. He was a machinist all his life and is selling his whole shop and some of his equipment is like new and very well tooled. He lives over around Pittsburgh. Give him a email and he will tell you what he has. He would like to sell all at...

Rndmann9 The question of melting all your chips is a very good one. What I do when I gather up the chips I place them in a cut open soda or pop can, then I bend over the edges and crush the can down as much as I can. When I melt my other metal and the crucible is molten I will put the can of...

Bob Very nice work. Nelson

Ken That is a very beautiful set of engines. When I was quite young I had several Cox motors and enjoyed all the hour playing with them. The last job I worked at a young man there was into RC cars and he had tricked everything out to the max. But his father had a complete machine shop at his use...

Jim I just seen this thread and if I might suggest something try bumping your bentonite clay up to double what your recipe calls for. Bentonite is what make the sand hold together and it looks like your sand is quite crumble. If you can not do the fist full of sand compressed and get a good rock...

What you would mill will on the lathe is what you can dream up. If you can hold it you can drill or mill it. Nelson

You are right it is aluminium and I believe that is the reason for not using the tail stock. But cutting like he did held everything up close to the head or chuck which takes a lot of the vibration out of it. The most impressive thing to me was how he did his throw. Emergency collets are very...

Edi I am very impressed with your tiny 4. Your crankshaft was very impressive and I saw something that might be another method that looked very effective. The video is: Enjoying your build. Nelson

Any one wanting to spin anything that fast is playing games. I would hate to see a tool come apart or metal flying at that speed. High speeds are good for one thing and that is very small drill and end mills. Spinning anything on the lathe would require carbide or more durable cutters and a very...

When I hooked up my motor the VFD it was set on a slow ramp up and slow ramp down. I wired it to the motor to make sure it would work. It did not work and I was so upset, then I thought to check the motor wiring. There was the problem it was wired for 408 three phase. I rewired the motor for 208...

I may be wrong but I was told to keep the VFD at a 10% up or down and it would last a long time. I run my mill at 45 htz to 80 htz. I have not had any problem with it for 2 years now.

The VFD will reverse the rotation with out any help. Your switch will over load the VFD an shorten it life greatly. If you look at your poorly wrote manual there might be something about the wiring bar and what you have.

Gail I read you post and was kind of upset by it. There is only one way to run a lathe with disabilities or with out. Running a mill is the same and yes it is nice to have something to just push the button and watch, but in a real world its about what we want and the pain or adjustments to do...

Hi All, Holiday wishes and a Merry Christmas to all. When it get to disabilities the worst to me is pain and I have found the more I do the better I feel. Hearing is something I never paid much attention to and now it's too late. Hearing is one of our senses we really need when running...

Terry I've followed many builds but none like yours. You have a very special way of showing and explaining that anyone can follow. The greatest thing we can feel your excitement and your sorrow when thing are not quite right. You are an amazing person both in talent and words. Maybe one day we...
